Meiosis only occurs inreproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and...
Meiosis in humans occurs in specialized cells of the testes in men and the ovaries in women. Whereas mitosis creates cells identical to the original to replace dead cells or contribute to the growth of the whole organism, meiosis generates cells called gametes designed to fuse with gametes from...
What type of cell division gives an exact copy of the original cell? A. Mitosis B. Meiosis Which type of cell division answers somatic growth in an organism? Which of the following best describes what occurs during Gap 1 of the cell cycle? a. The nuclear membrane reforms....
Unlike mitosis where only one division occurs, cells undergoing meiosis experience two cell divisions. The first division is similar to mitosis and results in two daughter cells with the same number of chromosomes as the mother cell. These two daughter cells then experience a second division to ma...
What event occurs in both anaphase of mitosis and anaphase II of meiosis II? What stimulates the secondary oocyte to complete meiosis ii? What happens during metaphase I of meiosis? What happens in metaphase of meiosis 1? What would happen if meiosis did not occur in sexually reproducing organi...
An egg, or a sperm each contain 23 chromosomes, one of each pair (ideally), so when fertilization occurs, the fertilized egg will contain 46 chromosomes, exactly 23 from each of the egg and the sperm. Meiosis is divided into two cell divisions, meiosis I and II. In meiosis I homologous...
One major difference between mitosis and meiosis that can contribute significantly to genetic diversity in offspring is referred to as "crossing over" or "chromosomal crossover." Crossing over occurs only in meiosis. Homologous chromosomes can physically "swap" chromosomal segments, thereby ensuring that...
In which stage chiasma formation occurs? The chiasmata become visible during thediplotene stage of meiosis prophase Ibut the actual "crossing-over" of genetic material is believed to occur during the previous pachytene stage. Stages of Prophase 1 of Meiosis with a visual mnemonic ...
Both mitosis and meiosis are types of cell division that involve the segregation of chromosomes into daughter cells. However, there are many important differences between these two cellular processes.Mitosis is considered an “equational” form of cell division — it occurs in cells that do not ...
What event makes meiosis a reduction division and why does it make it a reduction division? What are some characteristics of the different types of cell division? What is type of cell division that occurs in somatic cells? Which was the first cell or cell-type...
